U.S. Nuclear Regulatory Commission ND-22-0002 Enclosure Page 2 of 5 IT AAC Statement Design Commitment 4.b) The components identified in Table 2.3.9-2 perform the listed function after receiving a manual signal from DAS.

Inspections/Tests/ Analyses Testing will be performed on the igniters using the DAS controls.

Acceptance Criteria The igniters energize after receiving a signal from DAS.

ITAAC Determination Basis Testing was performed in accordance with Unit 3 preoperational test procedures listed in Reference 1, to confirm the components identified in Combined License (COL) Appendix C Table 2.3.9-2 (Attachment A) performed the listed function after receiving a manual signal from the Diverse Actuation System (DAS).

Testing was performed in two parts to verify the igniters energize after receiving a signal from DAS. In the first preoperational test procedure documented in Reference 1, Hydrogen Igniter Control Switches 3-DAS-HS213 and 3-DAS-HS214, at the DAS control panel in the Main Control Room (MCR) were switched to the ON position. A digital multimeter was then used to verify the Containment Hydrogen Igniter control relays in Hydrogen Igniter Control Panels 3-VLS-JC-001 (Group 1 ), and 3-VLS-JC-002 (Group 2), were energized. The Hydrogen Igniter Control Switches were then switched to the OFF position.

In the second part, the other preoperational test procedure documented in Reference 1 placed Hydrogen lgniters switches VLS-EH-GR1 (Group 1) and VLS-EH-GR2 (Group 2) to the ON position. The same relays verified as energized in the first part of the test were also verified as energized in this procedure; relays in Hydrogen Igniter Control Panels 3-VLS-JC-001 (Group 1 ),

and 3-VLS-JC-002 (Group 2). An inspection verified that each of the sixty-six igniters identified in Attachment A were energized by recording an overall increase of igniter temperatures at 1 O second intervals for 90 seconds. Switches VLS-EH-GR1 (Group 1) and VLS-EH-GR2 (Group 2), were then placed to the OFF position.

Unit 3 preoperational test results as identified in Reference 1 confirmed the igniters energize after receiving a signal from DAS.

Reference 1 is available for NRC inspection as part of Unit 3 ITAAC 2.3.09.04b Completion Package (Reference 2).

U.S. Nuclear Regulatory Commission ND-22-0002 Enclosure Page 3 of 5 ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all findings pertaining to the subject ITAAC and associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.3.09.04b (Reference 2) and is available for NRC review.

IT AAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.3.09.04b was performed for VEGP Unit 3 and that the prescribed acceptance criteria were met.

Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed ITAAC compliant condition in accordance with approved plant programs and procedures.
